T 0 all whom it 'may concern.' d

Be it known that I, JAMES U. DUFFY, a States, and a resident ofCleveland, county of Cuyahoga,y and State of Ohio, have invented Ta newand useful Improvement in Gar-Stop Shoes, of which the following is aspecification, the principle of the invention being hereinexplained andthe best mode in which I have contemplated applying that principle,so'as -todistinguish it from other inventions.

The present invention relates toshoes such as are adaptedV to be used incar stops of the type shown in 127 6273 dated August 20, 1919', grantedto Edward Breyley and myself and in `my copending application' SerialNo. 329724,*iiled October 10th,' i919. j f y These shoes' are adaptedlto receive the wheel or wheels of a `railway car or the like and arethen adapted to slide along under the wheel until the friction betweenthe shoe and the rail brings the slioe,'andrto a stop. The' shoes areconstructed so as to receive'eith'er oneror'both' wheels of a car truckandn are sodesigned that the wheel is lifted away from the rail.-

and carried in the shoe itself. The shoes d vcar until the forward leg11 of the shoe conare so formed that "when the car. is move backwardlythe shoe is' returned with the lcar until the shoe is prevented frommov- -p ingl farther by any suitable `type of stop placed'either on oradjacent the rail.,` It is, of course, understood that the shoes aregenerally used in pairs, rail, and these shoes there being one on eacwill be mounted on therails so as to receive the wheels of the truck atthe same time.'` To the accomplishment of the@ foregoing and relatedends, said invention, then, consists of :themeanfs "hereined out in theclaims. Y i 1 A The annexed drawing and the following description set'forth in detail certainmech-A anisin embodying the invention, 'suchdis# closed means constituting,"-however, but `one principle of theinvention may-be used.

Insaid annexed drawing:

Figure 1vis` a side elevational view of a rail and shoe embod ng myinvention; Fig.

- 2 is a similar view o-f a yslightly modified form of shoe: Fig?)v is asimilar view of another form of shoe showing the normal' position of thewheels indotted lines: Fig.;

In the form sho-wn in 1there isa rail 1 upon which is mounted Va slice 2which is provided with legs and 11 passing down vover the ball orf-therail,` which maintain the shoe in positionthereon. 'At one endif of therail there isf mounted a'bumper 5 yof the usual type and at the otherend. of the"- rail is shown a permanent stop 6 which is adaptedto limitthe forward orreturn movement of theshoe. U.' Spi Letters Patent No.

'vent the'A wheel from jumping out of the curved portion and rollingbeyond the shoe. The inclined forward surface 7 is high enough so that'the curved portion 8 which .receives the wheel'lies belowV the upperplane of the inclined portion, thus forming a hump v10 which preventsthe wheel from rolling out of the shoe upon rear movementof the tactsthe block mounted on the rail and thus f revents further movementofthevshoe.

InFig. 2 I have shown a slightly modified 13 as in the first form, andwhich is mounth ed on the rail A111 provided with'permanent sto-ps 15'and 16 ahead of'and behind-:the shoe to l'mit the movement ofthe shoein both directions. This shoe isprovided with a rear portion 17 of.approximatelytlie same height asfthe rearportion ofthe first formf y andit also clined A portion 18 which tapers off to the rail, but this'inclined portion 18 is spaced away from the rear portion a sufficientdistance tovallow both Vwheels of the truck to The forward wheel 19 rearportion A the curve 21 adjacent the top forward portion of 'the shoe."This shoe operates exa'ctly as the 'shoe in thel first form mentioned,except that both wheelsare carried by the shoe ,and the Vhump ispro-vided with'legs l hasa forwar-dlyk in- 10 is adapted to prevent thelwheels from f .between the. rear .portion the same until the forwardleg of the shoe contacts the stop l5 mounted on the rail.

-The remaining figures show another vform of shoe having 'the usual legs25 which exi tend downwardly and embrace the ball of the rail, the shoebeing provided with theV rear portion 26y having the curved `seat 2'(v'-forthe wheel and being also provided with the inclined front portionwhich has a curved surface 29 toward the Vrear portion, asin the otherforms. l`In this `form the distance Vbetweenthe curved seat `27 in therear portion and the .hump is slightly greater than in the formsliown inFig.l 1, thus allowing the'forwardpwheel 30 of the truck to have somerolling movement The Shoe is long enough, however7J toallow vthereargwheell ofthe truck to ridefupon the inclined-,forward portionv '28.when lthe ,shoe is acting to Vstop lthe canthewwheels when this.A isibeing done, being .indicated by dotted lines ,in Fig. 3. When the car isi 'ppuiled rearwardly, the rear wheel 3l. off the truck. rolls, off the'shoe, while the forward '..vvheel 30 rides upfagainstfthe hump 10 and l'pullsfthe shoe alongwithf the ear and wheel until thele'gs25 ofthe shoe.contact the fish plates 32 betweenfthe rail ends.

yThis section shows-the'forward legs, 25 yof. vthe shoe as contactingkthe ends of these -plates 321 to yprevent Vfurther movement; of

the shoe, thus allowing the wheels to' be withdrawn fromthe shoe. Fig. 5shows the form ofthe legs of the'shoe'which'embrace the ball of therail-andjthus'hold the shoe vin Iplace thereon.

n the present formi of 'shoe' the hump,

, combined with the curved portion ofthe shoe adjacent `the same servesto act as a return .of the shoe, this hump being so proportionedathatthe shoe will return Vwith the car wheel until itengages the stop orfish plate on'the rail, at which time'the shoe will be prevented fromfurther movement Ythus off Vthe shoe. i 1.50. have 4shown permanentstops Vmounted `on.
